    Surface core-level shift energy scan photoelectron diffraction (PED) was used to distinguish the two structural models of the C-terminated β-SiC(001)-c(2 × 2) surface under debate. An experimental PED curve of the surface C 1s component is in good agreement only with the simulated curve of the unusual bridge dimer model denying the conventional dimer model. The optimized structural parameters of this bridge dimer model are 1.22, 1.84 and 2.7 angstrom for the C-C, C-Si and Si-Si bond lengths, respectively, in agreement with recent theoretical calculations.
